public class ChunkedOutputStream
extends java.io.OutputStream

Implements HTTP chunking support. Writes are buffered to an internal buffer (2048 default size). Chunks are guaranteed to be at least as large as the buffer size (except for the last chunk).

构造器详细资料

ChunkedOutputStream

public ChunkedOutputStream(java.io.OutputStream stream,
                   int bufferSize)
                    throws java.io.IOException

Wraps a stream and chunks the output.

参数:

stream - to wrap

bufferSize - minimum chunk size (excluding last chunk)

抛出:

java.io.IOException

从以下版本开始:

3.0

ChunkedOutputStream

public ChunkedOutputStream(java.io.OutputStream stream)
                    throws java.io.IOException

Wraps a stream and chunks the output. The default buffer size of 2048 was chosen because the chunk overhead is less than 0.5%

参数:

stream -

抛出:

java.io.IOException

方法详细资料

flushCache

protected void flushCache()
                   throws java.io.IOException

Writes the cache out onto the underlying stream

抛出:

java.io.IOException

从以下版本开始:

3.0

flushCacheWithAppend

protected void flushCacheWithAppend(byte[] bufferToAppend,
                        int off,
                        int len)
                             throws java.io.IOException

Writes the cache and bufferToAppend to the underlying stream as one large chunk

参数:

bufferToAppend -

off -

len -

抛出:

java.io.IOException

从以下版本开始:

3.0

writeClosingChunk

protected void writeClosingChunk()
                          throws java.io.IOException

抛出:

java.io.IOException

finish

public void finish()
            throws java.io.IOException

Must be called to ensure the internal cache is flushed and the closing chunk is written.

抛出:

java.io.IOException

从以下版本开始:

3.0

write

public void write(int b)
           throws java.io.IOException

Write the specified byte to our output stream. Note: Avoid this method as it will cause an inefficient single byte chunk. Use write (byte[], int, int) instead.

指定者:

write 在类中 java.io.OutputStream

参数:

b - The byte to be written

抛出:

java.io.IOException - if an input/output error occurs

write

public void write(byte[] b)
           throws java.io.IOException

Writes the array. If the array does not fit within the buffer, it is not split, but rather written out as one large chunk.

覆盖:

write 在类中 java.io.OutputStream

参数:

b -

抛出:

java.io.IOException

从以下版本开始:

3.0

write

public void write(byte[] src,
         int off,
         int len)
           throws java.io.IOException

覆盖:

write 在类中 java.io.OutputStream

抛出:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

Flushes the underlying stream, but leaves the internal buffer alone.

指定者:

flush 在接口中 java.io.Flushable

覆盖:

flush 在类中 java.io.OutputStream

抛出:

java.io.IOException

close

public void close()
           throws java.io.IOException

Finishes writing to the underlying stream, but does NOT close the underlying stream.

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 java.io.OutputStream

抛出:

java.io.IOException
